To all whom it may concern.-

Be it known that I, MARCUS Gnonrna citizen of the United States,residing at Manhattan borough, New York city, in the county and State ofNew York, have invented new and useful Improvements in Safety Devicesfor Scarf-Pins, Studs,'and other Articles,of which the following is aspecification.

This invention relates to a device by which such articles as scarf'pins,hat-pins, studs,and the like can be secured against loss or theft. Suchdevice can be made simple and cheap, and its features of constructionare set forth in the following specification and claims, and illustratedin the annexed drawings, in which Figure 1 shows the fastening or safetydeviceapplied to a pin or shank. Fig. 2 is a sectional view of thesafety device. Fig. 3 is a section as shown in Fig. 2 on a larger scale.Fig. 4C is a plan view of Fig. 3 sectioned along a: 00, Fig. 1.. Fig. 5is an end view of the slide in the clamp. Fig. 6 is a sectional view ofthe ball or clamp. Figs. 7, 8, and 9 are views corresponding,respectively, to Figs. 1, 3, and 4 and show a modification. Fig. 10shows the modified form of the device applied to a stud or screw.

The safety device hereinafter described comprises in its makeup a clampor body portion, whichis ordinarilymadein onepiece, and a slidenon-rotatively mounted thereupon the said clamp or body portion beingslotted to receive the slide to thereby positively prevent the rotationof the latter during its motion. In one form of the device the clamp orbody portion is of ball form, while in the other it is tubular. In thecase of the ball-shaped clamp it has a slot located diametricallyopposite to a perforation therein through which the stem of thehereinbefore-mentioned slide passes. In the tubular form of the articlethe wall of the tube is slotted at diametrically opposite points toreceive the slide.

The screw-stem a is provided with a head I) and an eye 0. The ball orother shaped clamp c has a slot f to receive the head I) of thescrewstem and an opening g to receive the shank or pin it. A nut iengages with the screwthreaded portion of the screw-stem. A spring j isinterposed between the nut and the said ball-clamp. The saidspring,which surrounds the screw-stem a, is inclosed by the shell orhousing is, located between said clamp and nut. The screw-stem has ahead, as shown, and is received in the slotted part of the ballclamp,and when engaged by the nut these parts will be locked together.

The clamp 6 need not necessarily be ballshaped, but of any desiredshape; but the ball shape has been found practical. The clamp may behollow or solid. The slide or stem a cannot turn in the clamp, but isslid one way or another as the nut 1) is rotated. By having thestem-head b flat and its seat in the clamp of like shape the stem iskept from rotating even when the pin or shank h is drawn out. The headI) is of such shape or size as not to slide out of the clamp in onedirection. The spring j maintains a certain hold or friction on the pinby the slide at, even if the nut is loosened, so that the device willnot drop off the pin, although free to be moved back and forth until thenut is screwed home.

As previously indicated, the clamp need not be ball-shaped, as shown byFigs. 1 to 6, inclusive. Upon reference to Figs. 7 to 10, inclusive, theclamp e (illustrated in said fig ures) is of substantially cylindricalform, it having diametrically opposite slots f in its body to receivethehead Z) of the screw-stem a. The head b is of circular form, which isnot the case of the head I). With the excep tion of the shape of theclamp, e and the head I) the modified construction is exactly like thathereinbefore described, and hence I employ the same characters to denotesimilar parts.

WVhat I claim as new, and desire to secure by Letters Patent, is-

1. A safety device comprising a clamp or body portion of one piece,aslide non-rotatively mounted in the clamp, and an actuating-nut for theslide, the clamp and slide having eyes for the passage or reception of apin or other article.

2. A safety device comprising a clamp or body portion of one piece ofmaterial and having an eye for the reception of a pin or shank, a slidenon-rotatively mounted in the clamp and having an eye adapted to bebrought into and out of register with the eye of the clamp, a nut forthe slide, and a spring and sleeve between the nut and clamp.

3. A clamp or body portion having a seat for a slide, a headed slidenon-rotatively mounted in the clamp, an actuating-nut for the slide anda spring and sleeve between the 5. A safety device comprising aball-shaped 15 hollow clamp or body portion, a slide mounted in theclamp, the latter having a slot to receive the slide to therebypositively prevent rotation of said slide, and an actuating-nut for saidslide, the latter and the clamp having eyes for the passage of a pin orother article.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing" witnesses.
